An object of the present invention is to provide a sugar chain array having a sugar chain immobilized thereon that is useful for detecting binding between an analyte and a sugar chain, and a sugar chain array having the sugar chain immobilized thereon that is capable of inhibiting non-specific adsorption and binding of an analyte without having to coat the sugar chain array with an adsorption inhibitor. A specific sugar chain is immobilized on the sugar chain array of the present invention, and is useful for detecting binding between the sugar chain and an analyte such as a pathogen of an infectious disease or an excretion thereof. In addition, in the sugar chain array of the present invention, when a base material is used that is coated with a polymeric compound having a unit having a primary amino group, a unit for maintaining hydrophilicity, and a unit having a hydrophobic group, the sugar chain is immobilized efficiently and non-specific adsorption and binding of the analyte can be effectively inhibited.
本发明的目的是提供一种糖链阵列,其上固定有糖链,可用于检测分析物与糖链之间的结合;还提供一种糖链阵列,其上固定有糖链,可抑制分析物的非特异性吸附和结合,而无需在糖链阵列上涂布吸附抑制剂。本发明的糖链阵列上固定有特异性糖链,可用于检测糖链与分析物(如传染病病原体或其排泄物)之间的结合。此外,在本发明的糖链阵列中,当使用的基底材料涂覆有具有伯氨基的单元、保持亲水性的单元和具有疏水基团的单元的高分子化合物时,糖链被有效固定,分析物的非特异性吸附和结合可被有效抑制。
